In December 1995 sam pies were collected from different water bodies located on the Island of Hainan, China. 195 species were found. Among these sampies, there were 187 Monogononta und 8 Digononta (Bdelloidae). Further rotifers belonging to five genera and to the Bdelloidae could not be identified to species level, because determination was hindered by preservation artifacts. Among the species found, Cephalodella qionghaiensis is new to science. Additionally, a new form of Keratella micracantha and a new variety of Notholca acuminata could be described.
